Fig. 1 illustrates one and is used for blowback road 10, the particularly fluid system on the blowback road of hydraulic pressure high-pressure service pump loop form.Said pump loop 10 has one totally with 12 function blocks represented, and it is represented with dot-dash wireframe image ground in by the hydraulic circuit diagram of Fig. 1.Said function block 12 has the connection part of a pump intake 14 and a pump discharge 16 forms.The high-pressure service pump 18 that is connected like this on the connection part draws together with its drive motor 20, and it is designed to a kind of suction pump in other respects.Secondly function block 12 has fluid outlet 22, the work mechanism that needs hydraulic medium that connection one is not drawn in detail on it, and it is connected on the fluid input 14 of function block 12 with its fluid output again.Have an out splice going splice 26 in addition, it for example can lead to the chip conveyor that does not draw in detail of said work mechanism.Above-mentioned application only is an illustrative, and replacing work mechanism also can be other hydraulic load, but for example form is the lift of hydraulic transmission case hydraulic control, oil hydraulic motor of fork truck or the like.Replace high-pressure service pump 18 also a low pressure pump can occur, perhaps function block 12 is connected in the oil hydraulic circuit by other relations, for example in a hydraulic pressure heat exchanger or the cooling circuit.
But except that a high-voltage switch gear 30, also connecting two 2/2-way high pressure selector valves 32 in the path of the guiding fluid that is leading to work mechanism under the said situation; 34; Wherein owing to the reason of Security one pressure-limit valve 36 is set at the input end of selector valve 32, its output terminal feeds a backflow scavenge pipe 38.2/2-way selector valve 32 is connected on the backflow scavenge pipe 38 through an adjustable throttle valve 40 at output terminal equally, and making can be through the circulation of throttle valve 40 realization fully pressure-free power for fluid.One corresponding fluids pipeline from the fluid input of work mechanism to the pump intake 14 of function block 12 is as another guide flow path 42.In path 42, be adjacent to be connected equally a current pressure switch 44 as lower pressure switch with fluid input 24; The back connects a filtrating equipment 46 to inlet 14 directions; Its pollution level can detect through a motor-driven pressure-difference switch 48, and it is installed in the bypass pipeline in the path 42 of leading to filtrating equipment 46.If filtrating equipment 46 is designed to the cleaning and filtrating equipment that refluxes in a kind of preferred implementing form, as under said situation, on filtrating equipment 46, connect backflow scavenge pipe 38 so, it can turn-off through backflow cleaning valve 50.Can measure the system value of fluid circuit in addition through sensor, for example pressure meter 52, for example hydrodynamic pressure.
Can supply with fluid to machine through said 2/2- way selector valve 32,34, shown in valve 32; Under 34 the closed condition; High-pressure service pump 18 feeds back the out splice going splice 26 to function block 12 through throttle valve 40 with fluid, so high-pressure service pump 18 can be designed with the metering pump of constant delivery power, when the work mechanism corresponding demand of not drawing in detail; Said selector valve 32,34 is opened by the specific time interval that disperses.Therefore also have such possibility, promptly guarantee constant filtration operation, wherein the fluid from fluid input 24 filters by means of filtrating equipment 46, be transported in the oil hydraulic circuit through pump 48, and through out splice going splice 26 output from function block 12 again.If filtrating equipment 46 is designed to the filter rinsed that refluxes, can start above-mentioned backflow cleaning process by hand so; But preferred consideration refluxes automatically and cleans operation, and its employing one is used for the swivel gear of each filter element, and it can be by means of a motor 54 controls, and this also will specify in the back.But filtrating equipment 46 can have only a filter element under the simplest structure situation, and it can use new filter element to change under contaminated state.
Fig. 2 illustrates function block 12 with the side view of a perspective, can see, the organization plan of the element of in Fig. 1, mentioning has been shown in Fig. 2.As press shown in the view of Fig. 2, whole functional piece 12 is done very for a short time together with built-in filtrating equipment 46 with a cuboid form structure, can be integrated in the function block 12 according to all elements by the blowback road 10 of the view of Fig. 1 with obviously saving the position.
In function block 12 enclosure interior; Guide flow path, particularly path 28 and 42 preferably interconnect in inside together with its bypass line like this; Make and form a kind of matrix structure of forming by the line and the file of conduction pipe; It has the fixed-site device that is used for installing the corresponding valve element of having mentioned in function block of being built in 12; Through above-mentioned fixed-site device scheme, except the matrix type linkage structure, make it can accomplish extremely a large amount of system tasks through corresponding connecting tube, wherein other valve elements can also be installed according to the difference of the function that the position fixture is hoped.Used fundamental system also can wherein also can adopt other valve elements at the position of the valve element that adopts up to now with the mode repacking easily at the scene of the compostle member of hydraulic pressure.Particularly when bigger flow and pressure occurring, also can reach the coupling of system at the scene.Except control valve commonly used and selector valve, also can adopt pressure-limit valve, one-way valve or other controlled control valves as the valve element that is used for the fixed-site device; The function block 12 that constitutes so also can be integrated in other hydraulic function systems, for example in the fuel tank unit of a mobile hydraulic system of not drawing in detail.
Make a kind of backflow cleaning type filtrating equipment at the filtrating equipment shown in Fig. 3 46, and have a cylindrical housings part 56 as filter housings.Above-mentioned filter housings spare 56 is installed on the end face of function block 12 along seeing to the direction of observation of Fig. 3, and embeds in the function block 12 corresponding housing members through the boss 58 of a stepped shaft.Housing member 56 is outwards widened through flange body 60, makes it on its bottom surface, have the mounting groove of the seal ring that is used for not drawing, with the sealing circle housing member 56 inside is sealed with respect to the external world.Therefore housing member 56 removably is connected with the housing of function block 12 through corresponding attachment screw 62 (referring to Fig. 2).Fluid supply for filtrating equipment 46; The housing of function block 12 has one and leads to the fluid passage 64 of fluid input 24; And another fluid passage 66 that feeds backflow scavenge pipe 38; It comprises reflux valve 50, this reflux valve 50 according to make by the view of Fig. 3 be screwed into cartridge form and load function piece 12 in.The pump intake 14 of function block 12 is shown on the left-half of Fig. 3 in addition, and it feeds the inside of function block and the inside that feeds filtrating equipment 46 housing members 56 through fluid connecting tube 68.
During upwards the filter element 70 of conical contraction is packed filtrating equipment 46 into, at the position of conical filtering element 70 the filter element (not shown) of partial cylindrical shape at least can appear also.The said conical filtering element of especially being made up of so-called wedge wire screen pipe filter element 70 leaves certain distance each other along a cylindrical circular arc line and is arranged in filter housings spare 56 and the function block 12 corresponding shell parts.For single filter element 70 is installed, function block 12 is equipped with a cup-shaped hole 72, and its boundary's wall aligns with the inwall of housing member 56.
Structure by the band filter element 70 of Fig. 3 is selected like this, so that can reflux cleaning; But in function block simple in structure, also there is such possibility; An i.e. only built-in so independent filter element in functional 12; Make it see that along its axial length roughly half is contained in the function block 12, in the particularly cup-shaped hole 72, second half stretches into housing member 56 inside from the bottom surface.Method filtrating equipment 46 can be built in the function block 12 with its functional element so that very compact mode is local in this way; In addition so also by means of the wall section of function block 12; Make filter element 70 avoid mechanical failure, because function block 12 is equipped with thicker wall thickness in the installing zone of filter element 70.It is chimeric reliably aspect heat power engineering, also to reach effective filter element, and this impels reducing of when filtering power loss, if medium particularly to be filtered is very different aspect serviceability temperature.
In pressing the selected structure of Fig. 3; Two filter elements, 70 outer direction of observations shown in removing are seen and radially another also are being set to filter element 70 from described two filter elements, 70 identical distance; One of them protrudes in the figure paper plane, and another is positioned at figure paper plane back.That is to say, with respect to the longitudinal axis 74 of filtrating equipment 46 four filter elements 70 altogether of mutual radial arrangement are set, they are provided with respect to the longitudinal axis 74 each other face-to-face in pairs.Here also can consider other configurations.Along seeing that to the direction of observation of Fig. 3 the filter element 70 on the right side is positioned at the top of another fluid passage 66, it is by means of the filtrating that is positioned at housing member 56 cleaning that refluxes thus.Here filtrating is passed the filter element of the cleaning that refluxes from outside to inside; The dirt that cleans through the backflow cleaning solution arrives the out splice going splice 26 of function blocks 12 through another fluid passage 66 and the backflow cleaning valve 50 opened, and dirty then backflow cleaning solution for example can flow to the chip conveyor of the work mechanism that do not draw in detail.
Other three filter elements 70 are connected on the fluid passage 64 with its corresponding bottom surface circlewise, and filtrating flows to filtrating equipment 46 from work mechanism through fluid input 24 through it.Therefore from inside to outside filter the high-pressure service pump that does not draw in detail 18 that filtrating arrives by Fig. 1 through fluid connecting tube 68 through single filter element 70.Because above-mentioned high-pressure service pump can be realized very high pumping power.Guarantee that according to the present invention fluid connecting tube 68 stretches out, and they can be overcome with respect to strong fluid flow corresponding resistance in the root area of conical filtering element 70 bottoms.Even in the root support region of widening for each filter element 70, also carry out effective filtration of special high level, total this again the energy of fluid system moved advantageous effect.
Can make each filter element 70 forward the backflow cleaning positions to and come back to strain position from its strain position successively by means of swivel gear 76, wherein both can also can carry out counterclockwise clockwise for rotatablely moving of each filter element 70.Swivel gear 76 itself have one be used for supporting endways each filter element 70 supporting member 78, wherein supporting member 78 is rotatably installed in the filter housings 56 by means of motor 54 wraparound rotating shafts 80.Above-mentioned rotational axis 80 overlaps with the longitudinal axis 74 of filtrating equipment 46 basically.
Supporting member 78 has two mutual aspectant end pieces 82,84, and each filter element 70 extends between them, and wherein lower end spare 84 has the passway that is used for FLUID TRANSPORTATION, and last end piece 82 externally that is at housing member 56 internal flows is sealed shut.If housing member 56 is taken off from function block 12, just can filter element 70 be extracted the element that more renews through last end piece 82 from function block 12.
The motor 54 of filtrating equipment 46 can be a motor; But preferably make a kind of form of pneumatic motor.The characteristic of above-mentioned pneumatic motor is; The output member of its axle journal shape carries out to-and-fro motion alternately according to the suction movement of pneumatic motor piston piece, and above-mentioned to-and-fro motion can be transformed into along the constant drive movement of filtrating equipment 46 turning axlees 80 driving directions by means of a free wheel device 88.The above-mentioned overdrive clutch device that is used for pneumatic motor is known, therefore here no longer specifies.But can make alternate reciprocating motion be transformed into the corresponding 90 ° rotation motion of the rotation that is used for filter element 70 by means of swivel gear 76 as the pneumatic motor 54 of drive unit with said drive scheme; So that in turn there is a transition element 70 to clean all the time at the backflow cleaning positions; And keep normal filtration work with other three filter elements, that is to say for filter element 70 corresponding backflow cleaning processes and can almost carry out with the continuous time lag; But also there is such possibility, promptly through for example confirming automatically respectively when it cleans for refluxing is suitable by means of the differential pressure measurement to filter element 70 of electronic differential pressure switch 48.
Because the conical structure of each filter element 70 adds that the cavity moulding of housing member 56 is confirmed; Said structure filter in service for energy-conservation advantageous particularly because significantly reduce in the flow resistance that normal filtration is in service when flowing through filter element 70 is formed by the resistance of the housing member of housing 56.Because said structure also causes the flow characteristic of laminar flow basically, the flow resistance when this helps to be reduced in the normal filtration operation, and guarantee directly to reduce with the filtration yield at fluid connecting tube 68 places of high-pressure service pump 18.
That had mentioned has the supporting rod to the inclination of the filtrating equipment longitudinal axis 74 directions with the preferential wedge wire screen pipe-filter element that adopts; So that under the situation of reserving the slit that to flow through by fluid,, wherein in each zone, contact position of iron wire and supporting rod, a solder joint is set with each circle of iron wire coiled.The gap size that is used for the fluid free flow, that is the distance between two slits prevent that dirt from flowing through, if particle size is greater than above-mentioned gap width.But the dirt that is stuck in the slit can be removed from filtrating equipment through described backflow cleaning reliably.The filter element 70 that cleaned so then returns to strain position from the backflow cleaning positions, and can directly be used for there continuing to filter.
For such structure is adopted in the supportings that filter element 70 is firm, promptly turning axle 80 had not only been guided in function block 12 but also in the filter housings 56 upper wall portions zones of filtrating equipment 46 endways.Therefore the vibration that in pneumatic motor 54, occurs had not only been passed in the fondational structure of function block 12 through housing member 56 but also through turning axle 80 reliably.This helps the oscillating component that reduces to be harmful to.The coaxial configuration that filter element 70 is installed with respect to turning axle 80 sealings is also guaranteed the operation of reliable in function, the backflow cleaning positions shown in wherein filter element 70 integral body move in this respect.
